PANEL John B. Anthony, -Berkeley, CalIf., assignor to Kaiser Engineers,Oakland, Calif., a corporation of California Application October 19,1945, Serial No. 623,223 4 Claims. (Cl. ins-6.5)

This invention relates to building structures, and more particularly itrelates to a panel for use in wall and roof structures of buildings.

Among the objects of the invention is the provision of a light weight,fire resistant panel which is economic and readily constructed. I

Another object of the invention is the provision of a wall and roofpanel provided with means for interlocking and aligned attachment withadjacent units.

A further object is to provide a sectional wall or roof element adaptedfor external use, which in cooperation with a plurality of similarunits, will provide an effective seal against the elements, as well. asagainst heat transfer.

According to the invention ther e is provided a panel for use in walland roof structures comprising a metal sheet adapted for exterior useand a cementitious slab, said metal sheet having a corrugated portionextending along its length and said slab having means on at least twoopposed edges for alignment with slabs in adjacent panels, and means forfastening said metal sheet to said slab in face to face relation. Theinvention also contemplates the use of a fibrous sheet for acousticalpurposes and insulation, as well as ornamentation. In buildingstructures a plurality of wall and roof panels in aligned relation areeach fastened to the framework of These and other objects of theinvention will be apparent from the specification and drawings, whichillustrate a preferred embodiment of the invention.

In the drawings:

Figure 1 represents a section of a wall structure showing a plurality ofassembled panels; and

Figure 2 represents an enlarged sectional view of one panel taken alongline 2-2 of Figure 1;

Figure 3 is a view in perspective of a panel as-. sembly slab.

The panel assembly when erected generally comprises a corrugated metalsheet II and a cementitious slab I2 fastened to an exterior supportingframework I3 preferably composed of substantially parallel structuralmembers by means of suitable bolts I I. The corrugated metal sheet II isadapted to serve as an exterior member and provide protection againstthe elements by virtue of its weather-proofing and waterproofingcharacteristics. The sheet II- may be of any desired thickness dependingupon the unsupported length of the sheet and the extent to which it isneeded for structural purposes. As shown in the drawings, it is adaptedto rest against the slab I2 in face to face relation therewith andadvantageously is of the same length as the slab. Its width may vary.and a single sheet may extend over the width of the slab or less, orover several slabs. The corrugated portions I5 run the length of thesheet II and are preferably rather large in cross-section so as toproduce a, cellular-like panel of sheet II and slab I2 which contributesstiffness to the sheet and an ornamental appearance.

The slab-s I2 are preferably precast, reinforced, rectangular tileformed of cementitious material such as calcined gypsum. In thepreferred form shown in the drawings, the slabs I2 are provided withtongue and groove means, respectively, on opposed edges for the purposeof providing alignment and interlocking with slabs in adjacent panels.Although, it is preferred to provide the tongue and groove arrangement I6 at all edges of slab I2, satisfactory results may be obtained if theyare on two opposed edges only. It is also useful to provide the edgesofslabs I2 with binders ll of metal or the like. The binders I'I givethe slabs straight edges so that true joints may be had and erectionfacilitated. The binders also protect the edges of slab I2, particularlywhere tongue and groove means are used, against chipping, breaking andother damage. The binders I! also provide a surface to which interiorfinishing material may be attached. The binders I! are advantageouslyinserted in the mold when the slab I2 is cast so that the ends I8 of thebinders may be anchored securely.

As stated previously, the cementitious material within the slab ispreferably calcined gypsum, al though hydraulic cement, clay or othersuitable materials may be used. In practice, it is desirable toreinforce the slab I2 so as to insure against failure in use. In thepreferred embodiment wire mesh I9 is employed. Obviously mesh I9 orwhatever other reinforcing means is used is cast integrally with theslab.

The slabs I2 and sheets II may be fastened together in any satisfactoryfashion. In the embodiment shown in the drawings this is accomplished byproviding bolts I4 which pass through holes 20 in slabs I2 and are inturn fastened to supporting framework I3 of the building structure. Arecess 2| is provided in the face of slab I2 opposite sheet II where thebolt head may rest.

An inner lining 22 may also be used which is adapted to rest against theother face of slab I2. This inner lining 22 may be of any materialswhich would serve as additional insulation against heat transfer, giveimproved acoustic 3 effects. or ornamentation or the like. In theembodiment shown in the drawings the material 22 is fiber glass and isused for acoustic purposes. The fiber glass 12 is-held in place by metalscrews 23 which extend into slab it. However, any suitable fasteningmeans may be employed.

It is to be understood that the inner lining 22 is not an essentialfeature of the invention in all of its uses and, accordingly, may bedispensed with in certain cases.

The present invention has several advantages. It provides a panelassembly which is light in weight, of sturdy construction. has goodinsulating qualities, is adapted for exterior uses, and which may bereadily erected with a minimum of time and expense.

The form of the invention shown herein represents the preferredembodiment thereof although variations may be made within the scope ofthe appended claims. For example, the corrugated portion of sheet II maybe reinforced by filling it with gypsum or other cementitious materialas shown at lia.

What is claimed is:

1; An exterior building wall including in combination a plurality ofexposed and spaced apart parallel structural members. an interior panelassembly comprising a plurality of interlocking pre-cast slabs of fireresistant material lying ad- Jacent one another and supported by andspaced from said structural members, a longitudinally corrugatedexterior sheet interposed between and contacting said structural membersand said slabs of said panel assembly and common fastening means forsecuring said corrugated sheet to said structural members and to saidslabs.

2. An exterior building wall including in combination a plurality ofexterior and spaced apart parallel structural members, an interior panelassembly comprising a plurality of interlocking 9 pre-cast cementitiousslabs lying adjacent one another and adapted to be rigidly supported bysaid structural members and spaced at a sub stantially equal distancetherefrom, heat insulat ing and sound absorbing members fastened to theinterior surface of said sla an exterior corrugated metallic sheetinterposed between and contacting said structural members and said slabsof said panel assembly, and fastening means members for securing-saidcorrugated sheekto said structural members and to said panel assembly.

3. An exterior building wall including in combination a plurality ofspaced apart and sub-- stantially parallel exposed support members, aninterior panel assembly comprising a plurality of pre-cast interlockingrectangular cementitious slabs lying adjacent one another and supportedby and spaced from said support members, a pinrality of exteriorlongitudinally corrugated sheets interposed between said support membersand said slabs, the troughs between said sheet and said slabs beingfilled with cementitious material.

and fastening means common to both said slabs and said support membersfor securing said panel ligssembly and said sheets to the supportmemers.

4. A structure for a building comprising an exterior supportingframework, a plurality of in-' teriorly disposed slabs of cementitiousmaterial, said slabs having means on at least two opposed edges forinterlocking engagement with adjacent slabs, protecting metallic bindermembers covering said edges and fixed to said slabs, an

exterior corrugated metallic sheet interposed between and in contactwith said slabs and said framework and common fastening means forsecuring said corrugated sheet to said supporting framework and to saidslabs.
